Exploring and Controlling Matter on Its Natural Time Scale

Attosecond Science: Status and Prospects

Physicists discover spiral vortex patterns from electron waves

University of Nebraska-Lincoln physicists have made a compelling discovery that graces the Sept. 11 cover of the journal Physical Review Letters. In their new study, physicists Anthony Starace and Jean Marcel Ngoko Djiokap report an unusual pattern of wave interference produced when an electron is ejected, or ionized, from its orbit around a helium atom.

Former students, post-docs, and collaborators of Professor Starace returned to UNL on Saturday, August 22 to deliver talks on hot topics in Atomic, Molecular, Optical & Plasma Physics. All events were held in Jorgensen Hall, and the event welcomed nearly 80 attendees.

Starace received honorary degree from Russian university

Anthony Starace received an honorary D.Sc. degree from Voronezh State University, Russia, in June, 2014, and presented an invited talk. The award was in honor of a 17-year collaboration between Starace and VSU.

Nebraska-Kansas consortium studies how light interacts with matter

Observing what happens in 1-trillionth of a second—the opening moves in photosynthesis, for example—requires precision and extremely fast devices. University of Nebraska–Lincoln physicists are expanding their experimental and theoretical arsenals to help reveal how light interacts with atoms, molecules and nanostructures.

Study details laser pulse impacts on behavior of electrons

By solving a six-dimensional equation that had previously stymied researchers, UNL physicists have pinpointed the characteristics of a laser pulse that yields electron behavior they can predict and essentially control.

UNL physicists model potential 4-D imaging technique

How electrons rearrange when atoms or molecules come together is the essence of chemistry, and the ability to manipulate those rearrangements is the goal of the emerging sphere of nanotechnology. A fuller understanding could lead to enormous scientific and technological breakthroughs.
